Hello, I'm new to the forum and the matrix. I Have an 04 with 160,000miles on it. I'm close to taking it to the mechanic but wanted to see if I could get some helpful advice here.
Well I've only had it a month or so, it's always had a rough idle and ran rough at high speeds but I've been working on it and it had been getting better. The engine gave me a "miss in cylinder 3" code so I changed spark plugs checked some things and finally did a compression test. The result where food in cylinder 1&4, but #3 had no compression wet or dry and #2 would tick up to 50psi on each crank then fall to zero.
From what I'm reading, it sounds like a head gasket but there are no other symptoms. No oil in the coolant. No overheating. I know it sat for a while I'm wondering about stuck valves? I'm new to gas cars (I have a diesel rabbit '81)so I don't completely understand them though I'm learning quickly. Any advice would be appreciated. I'm been looking for a leak down tester but if it were a problem beyond the valve cover of probably take it to a shop anyway. Thanks!
